Update Jan 31, 2018 This is verified (by me, at least) to work on both the official XenServer 7.2, and with the experimental xcp-ng. I've also semi-automated the process with these Ansible bits for new hardware / pool upgrades. Don’t get me wrong, XenServer 7 is a huge improvement over previous versions, and still my product of choice for those that don’t want to pay a literal fortune for vmWare licensing.
